Kuseri kwekubudirira kwetekinoroji mukuchaja mota itsva nekukurumidza uye mainjini endege anoshanda zviri nani, kune chinhu chinoratidzika kunge chakajairika asi chine simba -zviumbwa zvesimbi zvesilicon carbideIyi ceramic yepamusoro inoumbwa nezvinhu zvekabhoni nesilicon, kunyange zvazvo isingawanzo kutaurwa nezvayo semachipisi nemabhatiri, yava "gamba rakavanzika" muminda yakawanda yepamusoro nekuda kwekushanda kwayo "kwakaoma".
Chinhu chinonyanya kuzivikanwa nezve silicon carbide ceramics ndechekuti "inochinjika zvakanyanya" munzvimbo dzakanyanya. Zvinhu zvakajairika zvinogona kuora kana zvikanyanya kupisa, zvakafanana ne "heatstroke failure", asi zvinogona kuramba zvichikwanisa kuchengetedza simba razvo rinodarika 80% kunyangwe pa1200 ℃, uye zvinogona kutomira zvakanyanya pa1600 ℃ munguva pfupi. Kudzivirira kupisa uku kunoita kuti zvisiyane zvakanyanya mumamiriro ekupisa kwakanyanya, senge kuva chinhu chikuru chezvikamu zvinopisa zveinjini dzendege. Panguva imwe chete, kuoma kwayo kuri kwechipiri kune dhaimani, nekuomarara kweMohs kwe9.5. Pamwe chete nekuramba ngura kwakanaka, inogona kuchengetedza kugadzikana munzvimbo dzine acid yakasimba nealkali, uye hupenyu hwayo hwekushanda hunopfuura zvakanyanya zvinhu zvesimbi zvechinyakare.
Muminda yemagetsi nekutarisira kupisa, silicon carbide ceramics yakaratidza hunhu hwe "mutambi wezvinhu zvose". Kufambisa kwayo kupisa kwakapetwa kakawanda kupfuura kwesimbi dzechinyakare dzealumina, izvo zvakafanana nekuisa "heat sink inoshanda zvakanaka" pamidziyo yemagetsi, iyo inogona kubvisa nekukurumidza kupisa kunokonzerwa panguva yekushanda kwemidziyo.
Mazuva ano, kuvapo kwesilicon carbide ceramics kwapararira munzvimbo dzakawanda dzinokosha. Mumotokari itsva dzesimba, yakavanzwa mu power module, zvichideredza nguva yekuchaja uye kuwedzera daro; Mumunda wendege, zvikamu zve turbine zvakagadzirwa kubva mairi zvinogona kuderedza huremu hwemidziyo uye kuwedzera simba; Mukugadzira semiconductor, hunhu hwayo hwekuwedzera kupisa hunoita kuti michina chaiyo senge lithography michina ive yakarurama uye yakagadzikana; Kunyangwe muindasitiri yenyukireya, yave chinhu chakakosha chekuvaka reactors nekuda kwekubatsira kwayo kudzivirira mwaranzi.
Kare, mutengo waive chipingamupinyi pakupararira kwesimbi dzesilicon carbide, asi nekukura kwetekinoroji yekugadzirira, mutengo wayo wakadzikira zvishoma nezvishoma, uye maindasitiri akawanda ari kutanga kunakidzwa nekubudirira uku kwezvinhu. Kubva kumotokari dzemagetsi dzekufamba kwezuva nezuva kusvika kundege dzemuchadenga dzekuongorora nzvimbo, chinhu ichi chinoratidzika sechisingaonekwe se "pfupa rakaoma" chiri kutungamira tekinoroji kune ramangwana rinoshanda uye rakavimbika nenzira isina kujeka asi ine simba.
